Peregrine Falcons, Bald Eagles and Ospreys Oh My!

The peregrine falcon, the American bald eagle and the fish eating osprey are indicators of a healthy environment.  I am thrilled every time I see one of these birds along the shoreline of the Great Lakes.
Before DDT was banned, these birds had become nearly extinct in this area.  After DDT was banned, the Great Lakes very slowly purged of this economic poison that had magnified in water through food chains.  These birds at the top of the food chain started to return.

Rachel Carson's book, Silent Spring, made people aware of what was happening to our environment.  Citizens (and I was one) went to their local governments and state governments to protest the widespread use of DDT.  Finally, the U. S. banned its use and Canada followed.

Read more about the Great Lakes and its fish, birds and ecology in my book, The Dynamic Great Lakes. Presently the best place to get the new updated book for $9.95 + s&h is from the publisher:
